14. An apparatus according to claim 12 , further comprising a second warning/informing unit which warns and informs that no printing apparatus exists on the radio network, when it is determined on the basis of classification information of each electronic device acquired by said classification acquisition unit that no printing apparatus exists on the radio network upon generation of an instruction to transmit image data by said transmission instruction input unit.
15. An apparatus according to claim 12 , wherein said apparatus further comprises an input unit which inputs image data, and when said transmission instruction input unit is operated while the input image data is displayed for a predetermined period of time after the image data is input, the image data is transmitted to the electronic device determined by said determination unit through said radio communication unit.
16. An apparatus according to claim 1 , wherein if communication with an electronic device determined by said determination unit with which data communication is to be performed fails while image data is being transmitted by said radio communication unit, said determination unit determines a new electronic device with which data communication is to be performed.
17. An apparatus according to claim 16 , further comprising a re-determination unit which performs control to cause said classification acquisition unit to newly acquire a classification of each electronic device constituting the radio network and cause said determination unit to determine, on the basis of the newly obtained classification of each electronic device, a new electronic device with which data communication is to be performed, if communication with an electronic device determined by said determination unit with which data communication is to be performed fails while image data is being transmitted by said radio communication unit.
18. An apparatus according to claim 16 , wherein if a classification of each electronic device constituting the radio network is newly acquired by said classification acquisition unit under the control of said re-determination unit, and it is recognized that there is one electronic device which can communicate, said determination unit determines the recognized electronic device as an electronic device with which data communication is to be performed.
